Review: SEARCH NO FURTHER - I bought 2 of these, a 20 oz for my daughter to take to Uni and a 30 oz for myself (currently OOS). I don't often leave reviews, as a lot things these days are mediocre at best and crap at worst. Not these 'beasts'!!! They are amazing! The seal fits really well and is easy to put back on if you remove it for cleaning, as I do. It keeps cold drinks cold for over 24 hours and hot drinks...I had a hot chocolate in mine and forgot it had been made. 4 hours later it was still piping hot, to the point I left the lid open for it to cool down!! The eco friendly straws and cleaning brush are a bonus, you don't often get them included with flasks/mugs (my partner calls then cups, I say he's wrong and they're flasks, but hey, potato potaato 🤷‍♀️ I have bought numerous other brands, both from desertcart and other places, in a long search for the perfect flask. And now I have found it. The old saying "buy it cheap, but it twice" is definitely true, as is "you get what you pay for". I actually don't mind paying more, for a product that genuinely does what it claims to do. And this product does. I have a kitchen cupboard full of plastic ones, metal ones, some leak, some are impossible to get clean, some can't go in the dishwasher, some are going rusty....I'm sure you get the picture. These Beast tumblers are worth every penny. I've spent less on others, which ultimately leak and I've spent more on one "dishwasher safe" one that is going rusty around the top now. If you are looking for a high quality flask, that can keep your drinks both piping hot and freezing cold (I'm intrigued about the icecream idea from another review 🤔) THEN THIS IS THE PRODUCT YOU NEED. What's more, there are so many different colours, with colour co-ordinated lids, the whole family can have their own with no confusion over whose is whose. Can't recommend these highly enough 👌
Review: Fantastic Product - I Got What I Paid For! - It is so rare to actually purchase something nowadays and genuinely get what you pay for! Or to put it in a better way, something of decent quality. As many cut corners or try to find ways to min-max profit, quality is rare (unless you pay exceptionally high prices for something), which not many of us can do and when you do get excellent quality for a reasonable price it's a lovely and rare feeling :) Pros: •Huge capacity 40oz (1136ml) Over a Litre •18/8 Food Grade Stainless Steel •Insulated Vacuum Layer •Hardwaring Slightly Textured Coating helps me grip. Great colours. •Decent quality Thick, Food and Heat Safe Plastic Lid, With clever leak proof seal and nice simple hinge. •Easy to clean, keeps an entire pot of coffee hot for at least 6 hours, keeps cold drinks cold (Ribena and Ice still had Ice in it all day). •Comes with Two Stainless Steel Straws and a Straw Cleaner. Nicely Packaged with a lifetime guarantee. •Simple, straightforward design, it works unlike other brands with smaller cups that I've tried which leak or break almost immediately. Cons: •Handle (Also cleverly designed and good quality moulding and material) sold separately but I can forgive this because of the exceptional quality and need to recoup material costs for production. To sum this up it inspired me to give it this glowing review which I rarely do, It's easy to maybe look at the price and think it seems a bit high but for less than thirty quid it really isn't, this simple design with quality materials IS NOT cheap to produce, they are making a profit but the price is fair and equivalent to a top end big brand, with I think better Quality and beats a cheap plasticy generic version with poorer materials hands down. Dont spend a fiver and dont spend fifty quid get this instead. Time will tell how well it lasts before the lid looses pressure or leaks or if it scratches, but I can tell for the quality it is, that even under my heavy use it should last for a fair and reasonable time, they do have a guarantee and I'll happily give Greens Steel more money for the next one even if its not under warranty. Buy One it's phenomenal! :)

### ⭐⭐⭐⭐⭐ Excellent 👌🏻
*by A***R on 21 January 2026*

This Beast tumbler is amazing. Keeps my water ice cold. 900ml is a perfect size as well, not too big and not too small. Tested it for leaks by turning it upside down and shaking it. 100% leak proof. I haven't used it for a hot drink yet? Not sure I will as I mainly use it for my filtered water. Haven't used the the straws or straw cleaner either yet. Nice little extra to have nonetheless. Get one you won't be disappointed!
